Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, each embodiment of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can appreciate that, in the various embodiments of the present invention, many technical details are set forth in order for the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can be realized.

A first embodiment of the present invention relates to a signal transmission system. In this embodiment, the signal transmission system includes a signal encoding module and a signal decoding module; the signal encoding module is used to receive an input signal, use at least two encoding protocols to encode the input signal, and output the encoded signal; the signal decoding The module is used for receiving the encoded signal, and decoding the signal using at least one decoding protocol. The encoding end encodes the input signal with at least two encoding protocols, and the decoding end performs at least one decoding protocol decoding. Since the new device access does not require an additional transcoding box, the composition is relatively simple, so the signal transmission system can be Adapt to a variety of application scenarios, improve the applicability of the signal transmission system and the efficiency of construction.

The module structure diagram of the signal transmission system provided by this embodiment is shown in FIG. 1 , including: a signal encoding module 10 and a signal decoding module 20 .

The signal encoding module 10 is used for receiving the input signal, encoding the input signal using at least two encoding protocols, and outputting the encoded signal;

The signal decoding module 20 is used for receiving the encoded signal, and decoding the signal by adopting at least one decoding protocol.

Here, the input signal refers to a signal that is not encoded. The encoding protocol may be but not limited to: H.264 encoding protocol, H.265 encoding protocol, JPEG2000 encoding protocol, SDVOE encoding protocol, M-JPEG encoding protocol, and other public or private encoding protocols. The signal encoding module 10 can encode the input signal through two or more encoders, wherein each encoder performs one encoding on the input signal; it can also form one encoder by integrating two or more encoding protocols together , and then encode the input signal with two or more encoding protocols. After encoding, the signal encoding module 10 can directly transmit the encoded signal to the signal decoding module 20 through ordinary lines (such as cables, optical fiber lines, etc.), or the encoded signal can be transmitted to the network first, and the signal decoding module 20 receives the encoded signal.

The decoding protocol corresponds to at least one of the encoding protocols, and may be but not limited to: H.264 decoding protocol, H.265 decoding protocol, JPEG2000 decoding protocol, SDVOE decoding protocol, M-JPEG decoding protocol, and other public or private decoding protocols. It should be understood that the signal decoding module 20 may include multiple decoding protocols, but at least one of the decoding protocols may be used to decode the received signal according to actual needs. Optionally, the signal decoding module 20 can decode the received signal through at least one decoder, or can integrate multiple decoding protocols into one decoder, and perform at least one method on the received signal through the integrated decoder. Decoding the decoding protocol. After decoding the received signal, the signal decoding module 20 outputs the decoded signal to a display device (eg, a display).

The following is a specific application scenario to illustrate:

Please refer to Figure 2, which is a schematic block diagram of a traditional audio and video signal transmission system. It can be seen from the figure that the transmission of audio and video signals requires an extender, a matrix switcher and a processor. The composition is relatively complex, and the system construction process It is cumbersome. When there is a new device to be connected to the system, it is necessary to reconfigure the extender, processor and connect the new device to the matrix switcher, etc. The construction efficiency is low and the adaptability is poor.

Please refer to FIG. 3 , which is a schematic block diagram of a traditional distributed audio and video signal transmission system, wherein the distributed audio and video signal transmission system performs core interaction through network switches. The signal is encoded, and then transmitted to the switch according to the network protocol; the decoder receives the signal from the switch and decodes it according to the corresponding decoding protocol, and outputs it to the display device. Although the distributed audio and video signal transmission system is relatively simple in composition, if the new equipment is different from the encoding or decoding protocol of the system itself, additional transcoding equipment (such as a transcoding box) is required to enable the new equipment to connect. The access process is also complicated and the adaptability is poor. For example, when connecting a network camera to a distributed audio and video signal transmission system whose codec protocol is JPEG2000, a special transcoding box is required. The transcoding box first performs the H.264/265 decoding protocol on the signal of the network camera. Decoding, and then JPEG2000 encoding protocol encoding. In addition, when the protocol of the distributed audio and video signal transmission system itself is a codec protocol such as SDVOE, the output signal cannot be soft-decoded on the terminal device (such as a computer, mobile phone or notebook, etc.), resulting in the terminal device unable to preview the screen. or echo, which is inconvenient for users to operate.

Please refer to FIG. 4 , which is a schematic block diagram of the application of the signal transmission system provided in this embodiment in the transmission of audio and video signals. Wherein, the signal encoding module 10 is an encoder for mixed encoding multi-stream output, such as encoder 1 and encoder 2 shown in the figure. Optionally, the signal encoding module 10 may include an encoder for hybrid encoding multi-stream output and an encoder for single-stream encoding output as shown in the figure. The signal decoding module 20 is a decoder for mixed decoding output such as the decoder 1 and the decoder 2 shown in the figure. Optionally, the signal decoding modulo 20 may include the decoder of the mixed decoding output and the decoder of the single stream decoding output shown in the figure. When the signal of the signal source 1 enters the encoder 1, the encoder 1 uses at least two encoding protocols to encode the signal of the signal source 1 to form a multi-stream output to the switch. The decoder 1 can receive the multi-stream audio and video signals transmitted by the switch, and output to the display device 1 after decoding. The signal of signal source 2 is processed in the same way as the signal of signal source 1. The processing of the signal of the signal source 3 may be a conventional single encoding and decoding process and then output to the display device 3 . It can be understood that the number of encoders for mixed encoding multi-stream output at the encoding end and encoders for single-stream encoding output can be set according to actual needs. You can set the corresponding code end accordingly. Since the new device can directly access the hybrid encoder of the signal encoding module when it is connected to the system, no additional transcoding device is required, so the system can be adapted to various application scenarios, with simple construction and high efficiency. In addition, the audio and video signals of codec protocols such as SDVOE can form signals of other protocols (such as H.264/265 codec protocol). Therefore, soft decoding can be implemented in the terminal device, so that the audio and video signals can be previewed or returned to the screen. display, which is convenient for users to operate.

Compared with the prior art, in this embodiment, the input signal is encoded by at least two encoding protocols through the signal encoding module, and the encoded signal is decoded by at least one decoding protocol through the signal decoding module, so that the signal transmission system can Adapting to a variety of application scenarios, the new equipment can be directly connected to the signal transmission system, without additional transcoding equipment, the construction is simple, the efficiency is high, and the adaptability of the signal transmission system is improved. In addition, for the codec protocol that cannot implement soft decoding, other signals that can be soft decoded can be formed. Therefore, these signals that cannot implement soft decoding can also be previewed or echoed on the terminal device, which is convenient for users to operate.

There is at least one signal decoding unit 201, and each signal decoding unit 201 uses a decoding protocol for decoding. The number of the signal decoding units 201 can be set according to actual needs, which is not specifically limited here. Optionally, the signal output unit 202 may be a signal selector or a signal processor, wherein the signal selector is also called a signal switch. All the signal decoding units 201 can output multiple decoded signals, and the signal output unit 202 can be configured according to actual needs to acquire and output at least one signal decoded by the signal decoding unit 201 .

Through the signal distribution unit, the input signal can be divided into multiple signals, so that multiple signal encoding units can be used to encode multiple encoding protocols, so that the signal transmission system can be applied to a variety of application scenarios and is easy to build; through the signal output unit, you can Selecting one or more of the multiple decoded signals of the output signal decoding unit enables the signal transmission system to be constructed according to the needs of the user and improves the construction efficiency.

The encoding protocol may be, but not limited to, H.264 encoding protocol, H.265 encoding protocol, JPEG2000 encoding protocol, SDVOE encoding protocol, M-JPEG encoding protocol, and other public or private encoding protocols. After encoding, the encoder transmits the encoded signal to the network or directly to the decoder through a line (eg, cable, fiber optic line, etc.). Optionally, the encoder integrates two or more encoding protocols, so that the encoding of at least two or more encoding protocols can be implemented.

Optionally, the encoder may divide the input signal into N signals through a signal distributor, and then use N encoding protocols to encode the N signals respectively. Among them, N is a positive integer greater than 1. After encoding, the encoder outputs the encoded signal.

It can be understood that, among the two or more decoding protocols, one decoding protocol corresponds to the encoding protocol of the input signal. Since the decoder can include a variety of decoding protocols, the device that can output the encoded signal can be directly connected to the network switch, and the decoder can also realize the decoding output after obtaining the signal of the device. For example, the network camera can be directly connected to the network switch, and the decoder can decode and output the signal of the network camera.
